IMPROVEMENT IN GLOVE WRlST-CLASPS.

Specification forming part of Letters Patent No. 197,751, dated December 4, 1877; application filed September 7, 1877.

To all whom it mcy concern:

Be it known that I, NELsoN VROOMAN, of J ohnstown, in the county of Fulton and State v of New York, have invented an Improvement clasps or fasteners having metallic levers pivoted at one end, and applied to the wrist-slit of a glove or mitten in a suitable manner, for.

the purpose of keeping the same open or closed, as desired; but my invention differs from others in having the spring constructed so as to press fiatwise, instead of edgewise, as shown in Lewines Patent of May 11,1875, N 0. 163,219.

In my invention some defects that exist in this class of clasps are obviated. I also secure greater elasticity and pressure of the spring by constructing it in such a form.

A, Figs. 1, 3, and 4., represents one of the arms, which is pivoted to the arm B on the pin b, shown in Fig. 2. The pin b being secured centrally'in the end of thearm B, and the arm A having a corresponding receptacle for said pin, as well as the spring, Figs. 5 and 6, it is obvious that the wrist-flaps (formed by the slit) are not unequally distended in opening and closing my clasp.

My pivot-joint can be constructed so as to occupy much less space than those heretofore used for the purpose, as will be readily understood by a reference to the drawing and a careful comparison of the various devices employed for the purpose.

The spring (3, Figs. 1, 5, and 6, is secured to the arm B and at the joint shown in Fig.

1 the arm A is placed between the arm B and spring 0. The arm A is provided with a lug or projection, d, on its lateral surface, as shown in Figs. 1, 3, and 4, and corresponding recesses or notches e are also formed in the lateral'surf'ace and atthe outer circumference of the spring-joint, which are intended to retain the lugs d of the arm A either in an opened or closed position of the arms A and B, as will be fully understood by reference to Fig. 1.

It is well known that when springs are used fiatwise they are capable of exerting a much greater elastic force than were the same force expended ed gewise.

In Fig. 1 is shown an extra boss, provided with notches c e, and secured to the face or flat surface of the spring 0; but the form of construction for the reception and retention of the lug d (shown in Figs. 5 a11'd6,) is to be preferred for simplicity.

The lug or projection d is wedge-shaped, or has its opposite radial surfaces inclined, in

order to enable it to emerge from the depressions e 0 formed in the spring G, as already described.

I attain another advantage in having the lug d and depressions c elocated on the lateral surfaces of arm A and spring 0, described,

which is that the depressions e 0 may be ar-.

ranged atthe proper distance from each other,

whereas Lewines device must, of necessity,

open about ninety degrees, in order to secure sufficient retaining-surface. 1

What I claim as my invention is In combination with the arm B of a glove wrist-clasp, the spring G, provided with notches or depressions c e, and lug d on the lateral surface of the arm A, and operating substantially in the manner and for the purpose specified.

NELSON VROOMAN.
